Problems with tmux / reattach-to-user-namespace about zplug HOT 24 CLOSED

I appreciate your detailed report. I want to fix its problem with you.

First, you should create a minimum zshrc something like below, please try zplug on it.

# minimum zshrc

source ~/.zplug/zplug
zplug "b4b4r07/zplug"
zplug check || zplug install

zplug load --verbose

I need to know about it in detail and then to reproduce because I use tmux and reattach-to-user-namespace too but that problem does not occur.

from zplug.

Upon changing my .zshrc and opening a new shell, I get another error I meant to open an issue for:

Installing...  b4b4r07/zplug
__version_requirement:10: bad math expression: operator expected at `Git-50'
Installed!     b4b4r07/zplug    (3.66s)
 ==> Installed all plugins to /Users/felix/.zplug/repos, successfully!
zplug: total wall-time 3.669167 sec.
iMac%

However, it does not crash! Interesting. I will enable plugins one by one and try to find the culprit

from zplug.

I keep my dotfiles on github by the way, here's my .zshrc.

from zplug.

So, I have changed my .zshrc to:

if [[ -f ~/.zplug/zplug ]]; then
    source ~/.zplug/zplug
    zplug "b4b4r07/zplug"

    # Triaging
    zplug "b5b4r07/enhancd", at:v1, of:enhancd.sh
    zplug "tarruda/zsh-autosuggestions"
    zplug "uvaes/fzf-marks"

    zplug check || zplug install
    zplug load --verbose
fi

and I get this output:

Installing...  b5b4r07/enhancd
__version_requirement:10: bad math expression: operator expected at `Git-50'
Installed!     b5b4r07/enhancd              (2.81s)

  Loaded tarruda/zsh-autosuggestions/completion-server-init.zsh

Note that it gets stuck at this point and won't progress. Also my computer has slowed down to a crawl, even after closing iTerm altogether. That was another thing I meant to report.

from zplug.

I have no choice but to reboot now, I cannot even open a new terminal or the activity monitor. Every letter I type in here takes seconds to appear.

from zplug.

Alright, I had to reboot, everything's back to normal. I did get a chance to see the Activity monitor, though. There must have been at least 50 zsh instances and for some reason activity monitor does not let you kill multiple processes at once. And opening emacs took too long to change my .zshrc, so I could not start a terminal to fix it.

from zplug.

Ok, so that is definitely related to loading tarruda/zsh-autosuggestions. I can see the terminal title changing from zsh to rm over and over again.

__version_requirement:10: bad math expression: operator expected at `Git-50'

This error is related to #39.

from zplug.

And my name is not b5b4r07 but b4b4r07. Some problems were already fixed. Please update zplug and try again. e.g.,

Installing...  b5b4r07/enhancd
__version_requirement:10: bad math expression: operator expected at `Git-50'
Installed!     b5b4r07/enhancd              (2.81s)

from zplug.

Alright I did zplug update and it did not fix the git Git-50 thing, but it does load now and tmux seems to work !! It must have been fixed within the last 24 hours or so, because I did a fresh zplug install on my work machine yesterday when I made the report 👍

from zplug.

Ah, the issue is back. I have applied #40 which fixed the Git-50 math expression errors, but I have tracked down the cause of this:

if [[ -f ~/.zplug/zplug ]]; then
    source ~/.zplug/zplug
    zplug "b4b4r07/zplug"
    zplug "zsh-users/zsh-syntax-highlighting"
    zplug "plugins/vi-mode", from:oh-my-zsh
    zplug check || zplug install
    zplug load --verbose
fi

Both zsh-users/zsh-syntax-highlighting and plugins/vi-mode run fine on their own, but when combined it causes the described behaviour in tmux. It may be related to babarot/enhancd#17?

Okay, I'll give it a try.

from zplug.

I found a couple of other things when trying to creating a docker image that reproduces the problem:

• zplug does not detect missing git, it just stumbles over "command not found"
• event with git installed, the initial install always fails (but all things seem installed):

Installing...  zsh-users/zsh-syntax-highlighting

Also, for what it's worth, I find " ==> Installed to /root/.zplug/repos but failed." very confusing, how about "Installation completed with errors" or something like that? It's currently telling me 2 things, where it's installing and whether it's failed, one being mostly irrelevant to the user and the other one being of high importance.

from zplug.

Thank you for your report!

zplug does not detect missing git, it just stumbles over "command not found"

Now, latest zplug will detect whether git command exists or not. see also L1732-L1736 and 32ca4b5. Does that answer your question?

event with git installed, the initial install always fails (but all things seem installed):

Yes. This problem is known issue for me. All things will be installed successfully. This message and error occur when the process ID of background job has conflicted. In fact, it rarely occurs. I am going to do something about that problem, for example, not to display the error message to the user directly.

Thanks! Sounds good to me. I will make this message clearly understandable.

oops, sorry. The cause of this problem isn't the confilct of the process ID in background jobs. I will investigate the cause with xtrace.

It seems like I am unable to reproduce the issue within a docker container, I have even tried my complete .zshrc and it all works. Could be sth OSX specific?

Zsh versions:

Ubuntu: zsh 5.0.2 (x86_64-pc-linux-gnu)
OSX: zsh 5.0.7 (x86_64-apple-darwin14.0.0)

from zplug.

After a zplug update just now, the tmux part of this issue seem to have vanished! It works pretty well when I create and remove a bunch of panes, so that's great. I'll try it on my work machine again. Should we consider this sorted then? I really don't know what it was that fixed it but with the most recent version of zplug it just works !! 👍

from zplug.

Just came back from holidays to my work machine, and the problem is still occurring here :S

Unfortunately, I cannot give any more information, other than that it's still OSX Mavericks (iMac).

The config above reproduces the problem for me:

if [[ -f ~/.zplug/zplug ]]; then
    source ~/.zplug/zplug
    zplug "b4b4r07/zplug"
    zplug "zsh-users/zsh-syntax-highlighting"
    zplug "plugins/vi-mode", from:oh-my-zsh
    zplug check || zplug install
    zplug load --verbose
fi

Also note that this error only occurs when using reattach-to-user-namespace (as per issue title)... I just confirmed it again.

Edit:

Note that I rm -rf ~/.zplug, and reinstalled. So it should be up-to-date.

from zplug.

So, if I put set -g remain-on-exit on in my .tmux.conf, the panes stay open and report "Pane is dead".

I find it interesting that old panes die when I create a new one.

from zplug.

Actually, it now seems that reattach-to-user-namespace has nothing to do with this... It happens also for set-option -g default-command "zsh", but not for: set-option -g default-command "bash"

from zplug.

Really, the only thing that seems to help is to take out zsh-users/syntax-highlighting. I guess I can live without it :)

from zplug.

Okay, I'll reproduce your problem.

from zplug.

@felixSchl Is this issue fixed/not due to zplug from what I see in the referenced issue?

from zplug.

@NigoroJr Correct. This can be closed.
